Heres the deal ok my decompression cam was ticking like crazy so i took the cam out and replaced it with a hot cam stage 1 and put a dg muffler on it now when installing the cam sprocket i tried like hell to get the marks just rite it wouldnt work so i got it the best i could which was very close so i put it together and broke tha cam in like it says to do now when i adj. my valves i notice the lash is .13mm and .15mm so i used the closest feeler gage i could which was a .127mm and a .152 that being said i broke it in and then went to ride it and it runs good starts good but when i punch it and getr to about 1/2 to 3/4 throttle it bogs down the picks up and to be honest it seems less powerful then before any ideas any hints no im running a standard plug and no carb mods have been made....what should i do please help

 

You probably need to rejet it and a free flowing filter. Its possibly starving for fuel and air due to the higher duration.
